Jet head for use in beverage filling machine for physical sterilization of e.g. bottle, has jet finger connected with vacuum housing such that vacuum housing with finger form permanent high vacuum-tight vacuum covering

摘要

The head has an electron source i.e. cathode (2), arranged in a vacuum housing (1), where the cathode is formed as a flat emitter or glow filament. A jet finger (3) includes an outlet window (5) at a distal end (4), where the outlet window exhibits layer thickness between 10 picometer and 20 picometer. The vacuum housing with the jet finger form a permanent high vacuum-tight vacuum covering (6). The jet finger exhibits a cross section, which is smaller than a cross section of the vacuum housing.
